You are entitled to your opinion, but keep in mind, it is only an opinion. If you don’t think you are living in a police state, you are sorely mistaken.
I agree we are approaching a police state. But that has NOTHING to do with what happened with Michael Brown. The results would have been the same 30 years ago. And that is my point - you are shoehorning the facts into your preconceptions and failing miserably in doing such.
